MARSHAL \YOOI), OF ALDERSON, \VEST VIRGINIA, ASSIGNOR TO HIMSELF AND ALEX. MCVEY MILLER, OF SAME PLACE.

APPARATUS FOR HEATING RAILWAY PASSENGER-CARS.

SPECIFICATION forming part of Letters Patent No. 397,212, dated February 5, 1889.

Application filed "February 14, 1888. Serial No. 264,017. (No model.)

To all 1077/0772 it may concern.-

Be it known that I, l\'IARSHAL IVOOD, of Alderson, in the county of Monroe and State of \Yest Virginia, have invented a new and Improved Apparatus for Heating Railway PassengeieOai-s, of which the following is a full, clear, and exact description.

The invention relates to apparatus for heating railway-cars, and has for its object to provide an improved means therefor in which the heated air is effectively conveyed to the several passenger-ears of a railway-train and without loss of room in the said cars.

The invention consists in apparatus for this purpose and in improvements in details thereof constructed and arranged as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 shows, with parts broken and partly in section, a portion of a railway-train, illustrating the heating apparatus applied thereto. Fig. 2 is a horizontal section through a passenger-car, showing a portion of this apparatus applied thereto, with parts broken away. Fig. 3 is a detail View, partly broken away and partly in section, of the fire-box of a locomotive with this invention applied thereto; and Fig. 4 is a detail view showing parts detached from the fire-box of the locomotive and beneath the cab thereof.

I11 carrying out this invention, 1 indicates the fire-box of the locomotive, through which pass air-tubes 2, having funnel-shaped ends 3 in position to catch the air as the train advances. The air-pipes 2 open into boxes or reservoirs 4, located in the fire-box l and connected by a series of small air-pipes, 5, which serve as grate-bars in the fire-box of the locomotive. The front boxes, at, are reservoirs for the cold air entering the funnels 3 of the air-pipes 2, and the rear boxes, 4, are reservoirs for the air which has been heated by passing through the pipes 5. The hot-air pipes 2 connect with a triangular-shaped heating-drum, 6, suspended in any suitable manner beneath the cab of the locomotive and connected by means of a pipe, 7, with a coupling, 8. The pipe 7 and the hot-air pipe 20 a project loosely into the coupling 8 and are provided near their ends with fixed disks 21, and between the said disks and the heads 13 is located a coiled spring,

To prevent the hot-air drum 6 from becoming detached from the coupling 8, it is provided with a spring hook-arm, 6, which passes through a perforated lug, 7, in the top of the coupling 8, and is held therein by means of the spring-leaf portion 8 of the hook-arm 6', the latter being adapted to move backward and forward freely therein. It will be seen by this construction that the ends of the pipes 7 and 20 have a free longitudinal movement through the perforated ends of the coupling 8, and are held in the normal position by means of the coiled springs 22. The pipe 20 is suspended in hangers 23 beneath the tender 24, and similar pipes, 20, are sus- 7o pended from each passenger-car 25 of the train by hangers 26, and practically form a continuous air-tube. A coupling is located between the first car and tender and between the several cars of the railway-train.

Each car is preferably provided with two registers, 27, each connected to the hot-air pipe 20 by means of a pipe, 28.

To aid in carrying the heated air through the pipes 20 into the several cars, the hot-air 8o drum 6 is connected by means of a tube, 31, with the steam-dome 32 of the locomotive.

By this means the force of the steam drives the air passing through the pipes 2 into and through the pipes 20 and into the several cars of the train.

It will be seen that by means of this apparatus the air, entering the funnel-shaped months 3, will be carried into the front boxes or reservoirs, 4, in the fire-box 1, and, passing 0 through the hollow grate-bars 5, will become heated and will be stored in the rear boxes or reservoirs, 4, and will then pass, by the force of the air passing through the funnel-shaped months 3, along the pipes 2 into the hot-air 5 drum 6 and through the pipes and registers 27 into the several cars of the train, thereby supplying them with heated air.

Having thus described my invent-ion, what I claim as new, and desire to secure by Letters Patent, is

1. An apparatus for heating railway pas senger-cars, consisting of air-tubes having open ends projecting in front of the fire-boxv oi the locomotive, passing through reservoirs in the fire-box connected by hollow tubes serving as grate-lmrs, and passing to a hotair drum, beneath the cab of the loconmtive, said hot-air drum being connected by a tube and flexible coupling with an air-pipe beneath the tender, which connected in turn with air-pipes suspended btmeath the ears of the train and )rovided with branch i )es and V I n pertorated openings ll] the floors ot the said. 5 cars, said pipes being connected together be- 1 tween the cars by suitable flexible couplin gs, substantially as described.

2. In an apparatus for heatin railway passenger-cars, the combination, with registeropenings in the bottoms of the said cars com nected with a main hot-air pipe leading to a hot-air drum located 'liieneath the cab ol. the locomotive, which in turn is connected by hot air pipes passing through the fire-box ot' the locomotive, with open ends proj ectingl' eyon d the same, of a steam-pipe connecting the hotair drum beneath the locomotive with the steam-driun, substantially as described.

3. In an apparatus for heating railway passenger-cars, the combination, with open-end air-pipes passing through the fire-box of: the locomotive and beneath the cars of the train and connected with suitable openings in the said cars, of reservoirs located in the fire-box of the locomotive and connected by tubular bars forming the grate-bars of the fire-box, substantially as shown and described.

et. In an apparatus for heating railway passenger-cars, the combination, with the fire box 1, of the air-pipes 2, having funnelshaped ends 8, and the reservoir-boxes at, connected by tubular grate-bars I, substantially as de- 1 scribed.

55. In an ap n'tratus 'for hezitting passenger railway-cars, the (:ombination, with the V shaped heating-drum (i, located beneath the cab of the locomotive and having a pipe, 7, connecting with the main heating-pipe located beneath the ears of the train, of airpipes 2, passing through the fire-box 1, having open ends and connected with the reservoirs -l, joined by hollow g1-ate-l a1.'s 5, located in the fire-box 1, substantially as described.

6. In an ap )aratus for heating railway passenger-cars, the con'ibination, with the heating-drum U, the air-pipes 2, connected with said heating-drum, passing through the firebox Land having open ends 3, and the reservoir-boxes 4- and grate-bars 5, connected with the said air-tubes 2, ol the stean'l-pipe 31,0011- necting the hot-air drum 0 with the steamdome 39, substantially as shown and described.

'7. An apparatus for heating passenger-ears of a rail\vay-train, consisting of the air-pipes 2, with openings 3,passin g through the lire-box 1 of the locomotive, connecting with reservoirboxes at and hollow grate-bars 5, and the hotair drum 0, having pipe 7, with coiled springs 22 1nd springhook 0, and 'l'reelyresting in the lug 7 of coupling Fl, and a series oi. air-pipe sections, 20, connected by couplings 8, and with registers 27 in the cars 25, substantially as shown and described.
